Serial No. 37,455.

Re it known that I, Y\"\7.u,i,ll\iu l). HAM- MOND, a citizen of the United States, resid-- ing at Boston, in the county of Suliolk and State of Massachusetts, have invented certain Improvements in Bumpers for Shoe- Racks, of which the following description, in connect-ion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to racks and particularly to racks of the type commonly used in shoe factories for receiving and conveying the shoes from one part of the factory to another, and is shown as embodied in the rack shown in my application Serial No. 835,728, filed May 1, 1914, of which this application is a division.

A great deal of trouble has been caused in the use of shoe racks, by the catching or interlocking of bolt heads or other projecting parts on one rack with portions of another. It is the object of my invention to provide a collision member or bumper whereby such difliculty may be avoided.

A. feature of my invention comprises a rack having a frame, and a bumper secured to each corner of said frame at its base, each bumper having a side face projecting laterally beyond the other parts of the rack and having an end portion projecting beyond the end of the rack which has a face forming a continuation of said side face and curved inwardly toward the rack. Other features of the invention, comprising certain arrangements and combinations of parts, will be described in the specification and pointed out in the claims.

In the drawings, which show a embodiment of the invention t- Figure 1 is a side elevation of the rack;

Fig. 2 is a perspective of a corner of the rack, showing the bumper; and

Figs. 8 and 4 are respectively a side elevation and a plan of the bumper.

The rack shown comprises a base frame consisting of two sills 2 of angle iron connected by cross bars, not shown, and two preferred end frames removably secured by means of bolts to opposite ends of the base frame. Each of these end frames consists of two corner standards 4 of angle iron connected at their upper ends by a cross tube 5 and near their lower ends by cross braces t3. l/Vhen the bolts l() by which the end frames are secured to the base frame, are removed, and the tie rod 9, which connectsl the cross tubes 5, is removed, the end frames may be folded down on to the base frame.

rIhe rack is provided with casters 20 secured to the bottoms of the sills 2 by means of bolts 22.

Racks, when being moved about a factory, are very likely to strike each other and to interlock where some part of one rack catches on a bolt head or other projection extending from another rack. In order to avoid this difficulty, the rack shown is provided at each of its base corners with a bumper 24 which is secured to the sill 2 by a bolt 26. The bumper 24 has holes 25, one of which registers with a hole in the sill 2. The bolt 26 passes through these holes and holds the sill-corners rmly in the right angled recess 31 in the bumper. In the rack shown this bumper is made of cast iron but it is obvious that any suitable material may be used. This bumper is shaped to fit around the corner of the frame of the rack and has an edge face projecting laterally beyond the ends of any of the projections at the side of the rack. This face is curved conveXly, as shown in Figs. 2 and 4 at 27. The forward end of the bumper projects beyond the end of the rack, the edge face of this part of the bumper curving inwardly toward the rack, as shown at 28. The opposite edge 29 of the bumper may be curved forward to produce a point at the forward end of the bumper and its upperface preferably is sloped downwardly toward this point as at 30, so that, if the bumper of one rack rides up on the bumper of another, it will tend to slide olf again and free the racks from each other. In the case of a collision between the rack and another rack, post or other obstruction, the bumper will usually strike the obstruction on its outer curved edge so that it will swing the rack away from the obstruction. The under side of the toe of the bumper is hollowed out, as shown in dotted lines.

I-Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In a shoe rack, a frame comprising base and end members, and a bumper secured to cach corner of said :trame at the base, each of said bumpers having a side face projecting laterally beyond the other parts of the rack and having an end portion projecting beyond the end of the rack, said end portion having a face forming a continuation of said side face and curved inwardly toward the rack, whereby said rack may be caused to glance away from objects struck by it as it moves in its path, without contact between such objects and any projecting members of the rack or its contents.

2. In a shoe rack, a frame comprising a base and end members, and a bumper secured to each corner of said frame at the base, each of said bumpers being shaped to it over the corner of the frame and having end and side portions projecting beyond the end and side portions, respectively, of the o rack, said bumper having its outer edge face curved conveXly from its forward to its rearward end and having its upper face curved downwardly and outwardly whereby an object which strikes and rides up on said bumper may easily slide 0E and away from contact therewith.

3. A bumper for a shoe rack, having end and side portions arranged to project beyond the end and side portions of the rack, and having its outer edge face curved con veXly from its forward to its rearward end, and having its upper face curved downwardly and outwardly whereby obj ects tending to strike the corners of the rack will be caused to glance off or slip over the bumper surface, thus protecting the contents of the rack from collision.

In testimony whereof I have signed my name to this specification.
